Jmmtcw b3 Pep/o 6/9 Patented Nov. 15, 1932 UNITED STATES DANIEL. n'mrsou BEPI DGLE, OI BERKELEY, CALIFORNIA, ABSIGNOB, BY DIRECT- IESNE ASSIGNMENTS, TO THE COMMERCE GUARDIAN TRUST & SAVINGS TRUSTEE, OF TOLEDO, OHIO PATENT OFFICE AIRWAY sucrro'n cLmna Application filed February a, 1928. Serial No. 251,641.

This invention relates -to manually portable electrically operated cleaners of the anway type in which tools and hose pipe accessories are operatively attachable to a tubular 5 handle thereof and is designed to utilize airway cleaning tools and air-way cablnets such as are described in my co-pendmg application for patent, Serial N 0. 15,529, filed March 14, 1925, and in my Patent No. 1,651,624, granted August 21, 1928. By the term air.- way as applied to cleaning devices I have reference to that type of cleaner having a hollow handle which provides an air passage or air-way communicating with a cleaningtool and with a source of suction, and in which the cleaning effect is obtained by the -erosivelike action of swiftly moving air, as more fully set forth in my copendmg application Serial No. 15,529, filed March 14, 1925. The objects of the present invention are to improve the form, manner and convenience of attaching and, removmgof paper dust filtering receptacles, to provide better position for the dust indicatonvalve and the electric connections on the suction or tubular handle, to provide a means for coohng the motor and to otherwise improve the apparatus generally.

To these ends the invention conslsts of the form, construction and arran ment ofipa'rts as set forth herein, and as 11 ustrated 1n the accompanying drawings in wh1ch:

Figure 7 is a detail designed to illustrate how the filtering receptacle is attached to receive the exhaust of dust laden air.

Figure 8 is a view similar to Figure 1, but with the upper portion of the dust collector broken' away for the purpose of illustrating the internal connections between parts, including the suction handle, the dust collector and the filtering receptacle.

In the drawings like characters of reference denote like and corresponding parts throughout the several views.

The straight section 1 of the tubular handle is intermediately joinedto the curved section 2 thereof by slip joints at the open end 1' and 2' respectively, of the'valve member 8 and it is further connected to the floor tool 4 at the slip joint 3. The said floor tool 4 is arranged to turn on theoswivel joint 5 so as to conform with the floor re ardless 01E variations in the angle of the ban 1e which is ri idly secured to the machine as a whole.

The motor 6 is rigidly attached with its axis parallel to the handle by means of the brace 7, and the valve housing 8 which isaligned with the handle, has. the nipple piece 9, connecting it with the L 10 by means of the knurled coupling screw 11. The other end oftthe L 10 connects with the body 12 by. means of thecap 13 which is designed to fit down on the concentric shield 14 so as to clasp the periphery-of the hole 14 of the paper filter 19 over the end 10' of the connectmg -L 10, so as to lead'within the filtering 'T 'eiknurled iring 15 runs onthe threaded 14, sealing-againstilea age and supporting fihe filter 19.

the filtering' enve ope 19 to kee it from be- A ing pressed against the inner we is or against its own folds; thus insuring f ee passage of air through its pores during i ation. Also A; suitable'niat. 20 which may be 'made of 1 straw or other light material is coiled with Y 9o 7 v L 10 back of the "cap 1'3 and is adapted to clamp the eriphery of the hole to prevent collapsing and shuttin oil the air flow from the interior of the lter, the extender 20' is placed centrally of the body 12 and directly over the passage leading to the fan 6 and 6".

Bands 21, 21 are used to further secure the body 12 to the handle 1 and they also sup port the ends of a truss 22 carrying the terminals 24 and 25 of the electric conduction cords 23 and 23 respectively. The terminal 24 is rigidly held fast while the terminal 25 is arranged to be slid into and out of electric contact by means of the sliding ring 26, which encircles the handle. The arrangement of the terminals and conduction cords is being claimed in my copending application 592,392, filed Feb. 11, 1932.

The cylindrical extension 27 of the fan case 29 has fitted to it, the lower end 28 of the body 12, in such manner that the intake of the fan 6', 6" is from the body 12 through a central port 34 in the lower end 28 thereof.

The exhaust port 29' of the fan-case is equivalent in design to the end of the handle tube 2 so that a hose pipe suitable for suction on the end of the handle may be attached to the exhaust 29, and used as a blower. Or-

. dinarily, however, a deflector plate 30 stifily hinged at 31 is arranged to throw exhaust air against the motor 6 for the purpose of cooling the same when in service.

The reason for hinging the deflector plate is to permit the same to be moved out of the way of the exhaust port 29 of the fan case to permit a hose pipe or suitable attachment to be secured to said exhaust.

A bracket 32 carrying a pair of rollers similar to the rollers 4', 4 of the floor tool is also secured at the hinge 31 and serves to support the device as a whole in the working position. The bracket 32 and the deflector plate 30 may be formed integral or separately, as desired.

The device in operation is designed to be drawn back and forth over the floor with the rear rollers elevated ordinarily above the floor for general sweeping; but may be tilted over the edges of rugs and the like by dropping the handle straight down so as to fulcrum on the rear rollers when they reach the floor. For running under furniture, the handle and body are swung over sidewise, swivelling at the joint 5.

The floor tool being removable, the lower end of the pipe or handle 1 may be provided with any approved modern tools such as may be used for stationary cleaning systems, including such as may have independently electrically driven parts. An outlet 33 on the motor 6 is provided so as to connect electrically from any independent source, or to furnish further extension of the current brought through the conduction cords 23, 23'.

In addition to the operative connection made with the cleaning tools at the lower end of the handle, the outer end of the curved handle tube is adapted to connect with hose p1 e or any suitable cleaning tool. 7

uring the cleaning operations the transparent-topped valve 8 must of course be kept within the housing 8, its port 17 registering with the open upper end of the L 10, the cylindrical portion 16 being adapted to interchangeably open and close the handle passages as the port 18 is rotated to register with either.

It is to be noted that by my present arrangement of the parts, the transparenttopped valve is brought near to the hand and eye of the operator of the device, as a sweeper, and facilitates observation of results when the dust laden air whirls through the valve 8'.

It is also to be observed by this present construction, the dust and litter of cleaning is arrested before the air carrying it passes through the fan. This arrangement favors compounding of the fan as shown, whereby the air passes through the centrifugal fans 6 and 6" consecutively and is thereby much accelerated and made more effective. To prevent the litter from reaching the fans in case of rupture of the filter 19, the first port 34 leading to the fan is covered by an arched circular screen 34 arranged in the lower end of the body 12.

When the filter 19 has become fouled or sufliciently filled, it is removed by first unscrewing the ring 11 so as to detach the L end from the member 8 then unhookin the cap 13 connected with the I said L, liftin them away with the filter attached. After the filter is outside the body it is released by unscrewing the ring 15 and sliding inward the end of the L carrying the shield 14. The filter envelope 19 with its contents is designed to be thrown away or destroyed and replaced with a new similar envelope made of porous paper on which advertising may be printed.

Replacing the filtering envelope is accomplished by first slipping the mouth 14 thereof over the shield 14 as detailed in Figure 7, then before reinserting into the body 12, laying it in laterality with the mat 20 and coil ing the two into spiral form. Then the coiled filter and mat are slid within the body 12 and around the distender 20 as shown in detail in cross section Figure 6. The cap 13 is replaced and again secured by suitable means against leak, the rings 11 and 15 are again screwed up, and the device is ready for further service.

Having now described the device and the manner of using the same, what I claim is:

1. An air-way cleaner having a dust coltachably connected at its mouth to an. in-

take tube adapted to direct dust-laden air into the interior of the filter envelope, means for preventing collapsing of said envelope, a suction pipe extending along the full length of and parallel with said dust collecting body rigidly connected thereto and movable therewith, the said suction pipe being adapted to be attached to dust collecting tools and being connected to said intake tube.

2. An air-way cleaning device comprising electrically operated suction means, a suction pipe handle, a dust collector body parallel with said suction pipe, a filtering receptacle within said body, a valve intermediate of the ends of said handle and an L pipe leading laterally from said valve and pro- 'ecting downwardly into said body, a cap lid secured to an end of said L pipe and adapted to close the end of said body, and the same end of said L pipe adapted to connect with and lead dust laden air into said filtering receptacle.
